COUNTER-RECOL-BEGULATNG MECHANISM.

Application filed 'May 7,

To ZZ whom 25 may concern.'

Be it l-:noxvn that l, BRYAN l). JOYCE, a citizen of the United States,and a resident of Davenport` county of Scott, and State of lowa, haveinvented an improvement in CorniterRecoil-Regulating Mechanism, of whichthe following is a specilication'.

The subject ot this invention is a valve for regulating the speed ot'counter-recoil in a recuperator mechanism.

The main objecto't the invention is the provision of means forautomatically varying the time which it will take 'for fiuid to pass:trom the recuperator cylinder into the recoil cylinder, uponcounter-recoil, to compensate for the position of elevation of the gun.Y

I attain the above object by a gravity actuated valve which varies thethrottling opening for return flow in accordance with the position ofelevation of the gun.

lVith the foregoing and other objects in view, my invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment ot' the invention herein disclosed maybe made Within the scope of what is claimed Without departing from thespirit of the invention.

A practical embodiment of the invention is shown in the accompanyingdrawing,

wherein:

Fig. l is a fragmentary view in longitudinal section of a recuperatorcylinder containing control mechanism constructed in accordance with myinvention;

Fig. 2 is a sectional vie7 taken on the line 2 2 of Fig. 1;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. i.

Referring to the drawing by numerals of reference:

A. recuperator cylinder is provided With a port 11 through which fluidmay flow from and to the recoil cylinder, not shown. lVithin therecuperator cylinder is mounted a housing 12 provided With a series ofinlet ports 13 some ot which ports are closed by a valve 14 normallyseated upon such ports and held upon its seat by a spring 15.

lVhen the fluid, due to recoil of the gun, rushes from the recoilcyiinder through port 11 into the recuperator cylinder it passes throughthe ports 13 and elevates the valve 14 against the action of the spring15, being 1923,v serial No. 627,243.

then free to pass through ports 16 into the throttling chamber 1'1".

lVhen the recoil ends and counter-r-ecoil starts, valve let is againseated thereby closing the ports 13, in which instance the returning:tluid passes through duct 17 formed in the housing, and thence througha port 18 and the apertures 19 formed ina disc like valve 20, which ismounted for oscillation within the casing on a pin 21 and which isautomatically moved to diii'erent positions as the gun is elevatedthrough gravity acting on a Weight 22 formed at the end of an arm 28which extends radially from the valve. From the apertures 19 the fluidpasses through a port 24- 'liormed in the casing and thence through aport 11 to the recoil cylinder.

From the foregoing it will be seen that as the gun is elevated more ofthe openings 19 are brought into register with th-e ports 18 and 24 thuspermitting a greater volume of fluid to pass in a given time throughsaid ports and thus compensating for the extra Weight to be returned tobattery.

I claim:

1. The combination with a recuperator cylinder provided with a port, ofa housing Within the cylinder provided with ports for the entrance oflfluid and with a duct and ports for the exit of fluid, a valve forclosing entrance ports against return flow and a gravity actuated valvemounted for oscillation in the housing provided with a series ofapertures one or more of which may register With the exit ports.

2. The combination with a recuperator cylinder provided with a port, ofa housing Within the cylinder, provided with ports for the exit of fluidand a gravity actuated valve mounted for oscillation in the housingprovided with a series of apertures one or more of Which may registerwith the eXit ports.

3. The combination With a recuperator cylinder provided With a port, ofa housing Within the cylinder provided with ports for the entrance ofiiuid and with a duct and ports for the exit of fluid, a valve forclosing the entrance ports against return floiv and means mounted in thehousing for varying the amount of opening of the exit ports inproportion to the elevation of the gun.

4. The combination with a recuperator cylinder provided With a port, ofa housing within the cylinder provided with ports for the entrance offluid and with a duct and ports for the exit of the fluid, a Valve forclosing the entrance ports against return ow and gravity actuated meansmounted in the housing for Varying the amount ofopening of the exitports in proportion to the e1e- Vation of the un.

5. The com inaton with a recuperator cylinder provided With a port, of ahousing Within the cylinder provded'wlth ports for the entrance of Huidand with ports for the exit of fluid, means for closing the entranceports against return HOW andautomatic means mounted in the housing forvarying the amount of opening of the exit ports in accordance With theelevation of thegun.
